Seat system for a vehicle for lifting and moving loads

A vehicle for lifting and moving loads, comprising:

• a chassis;
• a lift mechanism mounted on the chassis;
• a plurality of ground-engaging units including at least one selected from the group consisting of (a) wheels and (b) continuous track units, all of the ground-engaging units being steerable relative to the chassis, the chassis being supported on the ground-engaging units;
• a seat system comprising:
• an operator seat;
• a seat rotation mechanism operable in response to control signals to rotate the operator seat relative to the chassis;
• and
• a control system;
• operator controls mounted within reach of the operator seat of the seat system, said operator controls including:
• a steering control for selectively steering a subset of the ground-engaging units left or right relative to a direction of travel, whereby the orientation of the chassis changes relative to the ground in response to steering control inputs;
• and
• a directional control for selecting a direction of travel of the vehicle, and steering all of the ground-engaging units left or right together relative to the chassis to the selected direction of travel, whereby the direction of travel is changed without changing the orientation of the chassis relative to the ground;
• and
• wherein the control system of the seat system is operable to receive an input responsive to an operator input to the directional control and to output a control signal to the seat rotation mechanism to cause the operator seat to rotate towards the direction of travel.
